| 10 m.y. bin: | Cenozoic 5 | ||
| Key time interval: | Early/Lower Miocene | Zone: | Faunal Zone B |
| Age range of interval: | 23.03000 - 15.98000 m.y. ago |
Stratigraphy
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: The BSE Site is listed among "System B"-aged sites in Travouillon et al. (2006, Alcheringia, 30, Suppl. 1, 323-349).
The suboptimal stratigraphic nomenclature of Archer et al. (1997, Mém. Trav. École Prat. Hautes Études Inst. Montpellier, 21, 131–152) is replaced by a concept of faunal zones by Arena (2004, PhD thesis, Uviv. New South Wales, Sydney), confirmed by Travouillon et al. (2006). Faunal Zones A, B, C are identical to "Systems" A, B, C of Archer et al. (1997). Faunal Zone B is Early Miocene in age. | |||||
Lithology and environment
| Primary lithology: | "carbonate" |
| Lithology description: Fossiliferous rocks of the Riversleigh area are said to represent freshwater carbonates whose depositional history appears to involve a complex sequence of fluvial and karst processes (Archer et al., 2006, Alcheringia, 30, Suppl. 1, 1-17 and references cited therein). | |
| Environment: | cave |
| Geology comments: Boid Site East and Creaser’s Ramparts Site are freshwater limestone deposits which form part of more extensive Oligo-Miocene to Pleistocene limestone deposits within the Riversleigh World Heritage Area (Archer et al., 1989, 1997; Woodhead et al., 2014). Creaser (1997) suggested that Creaser’s Ramparts Site formed from a freshwater limestone pool in or at the edge of rainforest and that Boid Site East is a tufa deposit (Creaser, 1997). Arena (2004) classified both sites as vadose cave deposits that were deposited within Depositional Phase 2 (Travouillon et al., 2006). | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils,mesofossils |
| Preservation of anatomical detail: | excellent |
Collection methods and comments
| Collection methods: | acetic,survey of museum collection |
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: "Riversleigh fossils are rarely articulated but usually undistorted, can be completely freed from matrix with acid [...]." (Scanlon, 2006).
